摘要

A new 1D polyoxovanadate containing boric acid [Cu(en)(2)V10O28][Cu(en)(2)(H2O)](2)center dot 2H(3)BO(3)center dot 2H(2)O (1, en = ethylenediamine) has been hydrothermally synthesized and structurally characterized. Compound 1 consists of a polyoxovanadate chain [Cu(en)(2)V10O284-](n) based on the linkage of decavanadate clusters and [Cu(en)(2)](2+) groups, complex cations [Cu(en)(2)(H2O)(2+), free H3BO3 and H2O molecules. The polyoxovanadates and boric acid can undergo polycondensation into various B-O-V clusters under hydrothermal conditions, but 1 is the only example of the non-condensation of polyoxovanadate and boric acid. The IR spectrum and the thermal behavior of 1 were also studied.
